Everything looks good, but I vaguely recall a message from Takashi Iwai
(one of the main alsa developers) a long time ago that having both
analog and digital (IEC958) enabled at the same time could cause
problems. Because the aplay command worked via the analog output
(0:0), I am going to assume you want analog output.
By the way, the fact that aplay works means that alsa has identified
your hardware well enough to get a working driver loaded (with
hda-intel that doesn't necessarily mean the *best* driver), and so the
fact you don't have sound is a configuration issue, not a driver issue
at this point. Once you have sound, if some aspect doesn't work
correctly, it is time to revisit if the driver is the optimal driver
for your hardware.
You have IEC958 (digital output, 0:1) turned on and turned up.
Simple mixer control 'IEC958',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 39
Mono:
Front Left: Playback 29 [74%] [-15.00dB] [on]
Front Right: Playback 39 [100%] [0.00dB] [on]
Simple mixer control 'IEC958 Default PCM',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [on]
control.26 {
comment.access 'read write'
comment.type BOOLEAN
comment.count 1
iface MIXER
name 'IEC958 Playback Switch'
value true
}
control.27 {
comment.access 'read write'
comment.type BOOLEAN
comment.count 1
iface MIXER
name 'IEC958 Default PCM Playback Switch'
value true
}
See if you can use the alsamixer -c0 command interface to turn
these off. If you can't, you might have to use the command amixer to
do so. It is low level, but gives you access to everything. See
man amixer for how to use it.
Pulse looks like it is setup correctly, and once you take care of the
digital output, you should get sound.

Did you mean audacity or audacious? I tried the latter. No, it does not. Tried audacious with all sorts of settings, once again without understanding what I am doing, to no avail.

I use AC97 sound cards and they work fine. USB sound cards that adhere to the standard are supposed to work fine too, but I haven't experience with them either. Also, while I have pulseaudio installed, I have it disabled as the default device and don't start it on boot. So I can't help a lot with pulse stuff. There is a website, http://www.pulseaudio.org where you can probably get help. Others here might help you with pulse. The first suggestion is to go to the link below and run the shell script. It will print a whole bunch of information, much of it useful only for developers, but very comprehensive picture of your sound system. If you post it here, it allows people to see your sound setup, and perhaps spot a problem. You probably don't have any of the configuration from F10, but it would be great if you had run the alsa-info.sh program and saved the output so you could run it again and look at the differences. Good idea for next time. http://www.alsa-project.org/alsa-info.sh Run a wav file with aplay and see if it plays sound. aplay -D plughw:0,0 some.wav This will tell you if alsa has identified your device properly. Use something like audacity or amarok, which allows you to select the device to use, import an audio file, and see if it plays. Does the vu meter show sound while playing, even if it is silent? Try different outputs. What if you do the same thing after a pulseaudio --kill ? Have you run alsamixer to get the pulse volume control and turned it up? Go to the link below and download the latest driver snapshot. You can install it as it is supposed to be backward compatible, but that isn't necessary at this point. If you just unpack it, go into the directory that it unpacks to, something like alsa-driver-snapshot, and then into alsa-kernel/Documentation you will find all the driver documentation. Grep for your codec. Look at the HDA files for troubleshooting information. ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz I've had no major issues with sound in F11 x86_64, but I don't have hda-intel cards. I have pulseaudio installed, but don't use it. Before I disabled it, it seemed to work fine. -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
missing audio after F11 install on IBM T61 Thinkpad
Hi, I have been missing audio after installing F11 (from the XFCE spin) on my IBM Thinkpad T61. I looked around and even tried the following: http://forums.fedoraforum.org/showthread.php?t=206868&highlight=problems+sound but this did nothing. alsamixer -c0 brought in a while lot of stuff and I dutifully changed everything from to 00 without understanding the implications, but to no avail. Any suggestions? I sort of miss the old system-config-sound and then clicking to see whether sound would work on the older Fedoras (before 10). This machine had previously been upgraded from F8->F9->F10 so I never felt the problems in F10. I chose to install this time because of the ext4 filesystem, etc and hence getting sound working is a different ball-game. Thanks in advance for all the help!
